Help to get my girls in a home

On the 19th my now ex laid his hands on me and severely beat me leaving me black and blue for weeks. I lost everything leaving. I was a stay at home mom and he had control of all the money. Now we are trying to get back on our feet. I just want my girls to have a room with their bed in it. My oldest daughter is affected the most. She cries about losing the house but i have to explain to her i had to keep her and sister safe. Any help would be appreciated. I’m starting a new job soon thankfully but it is a cut from previous jobs. Just trying to make ends meet and get us in a home.
